Your staff is always cheerful and efficient. As a female usually traveling alone, I feel the security is very good, and with the valet parking I don't have to wander around in the dark by myself. And it's fabulous to have a bottle of cold water in my car when the weather is hot -- and to know that one of your nice guys will have turned on the air conditioning!
The drivers were very professional. The vans were so clean, and the seats were comfortable. Our car was ready when we got there. The payment desk was well organized, neat. The restrooms were SO clean. We also appreciated the water bottle offering, because you can get dehydrated when flying. Having the chance to sip water before the TSA line on the ride to the gate was great, and then having the chance to sip water on your ride home was even greater. These little touches make you feel pampered and you know that your car is safe. No hassles.
